To all whom it may concern.-

Be it known that I, WILLIAM M. PIATT, a citizen of the United States, residing at Mac-ochee, in the county of Logan and State of Ohio, have invented Improvements in Grain-Binders, of which the following is a specification.

In order that my invention may be fully understood, I will proceed to describe it with f chine.

Fig. XII is a view of a portion of the reel, showing a bat provided with a sliding knuckle. Fig. XIII is a top View of the reel-supporting arms and adjacent parts.

My main frame is constructedin substantial form of channel steel bars, for the reason that I have found this kind of bar preferable to an` gle steel bars or gaspipe for this purpose. A transverse section of the bar is shown in Fig. III. The frarneis formed of a bar starting with a straight portion, 1, parallel with the cutter -bar 21, forward straight portion, 2, curved portion 3, straight portion 4, curved portion 5, rearward straight. portion 6,eXtend ing as far rearward as a line drawn lengthwise through the middle portion of the main Fig.- V is an elevation of the ma-v platform 32, curved portion 7, straight portion 8, curved portion 9,"forward straight portion 10, curved portion 11,straight portion 12, secured to the portion 4, curved portion 13, rearward straight portion 14, curved portion portion 18, curved portion 19, and straight portion' 20, parallel with the Ycutter-bar, eX- tending under the portions 14 and 10-to'the center portion of thelatter, to which it is secured.

This frame is re enforced or strengthened by the opposite side of the end of theportion 20 of the bar. The grain endv of the platformframe is strengthened by a bar, 23, extending from the curved portion 17 to the end `of the divider. This form of main `frame provides a main frame having an opening, 26, for

the driving-wheel 27, a deep recess, 28, for the sheaf to fall through, a binding-table frame, 29, having forward extension, 30, connected by a neck-frame, 31, in front of the recess to the frame surrounding the driving-wheel and an ample platform-frame, 32, for the grain to fall on.

' 15, straight portion 16, parallel with the cutter-bar, curved portion 17, forward straight.'

8s 33 is ayoke-frame having arms 33 and 33b extending from the rear of the wheel-frame upward and then downward, hinged by short shafts 34 35 to the forward ends of bars 6 10 within the opening 26, and to the top of this frame 33 is journaledvby axle 36 the drivingwheel 27. To the rear of the frame 33 is secured a rack-segment, 37, engaged byawormshaft, 38, to provide means by which the main frame can be raised or lowered on the drivingwheel for regulating the height of cut at that side of the machine. cutter-bar on the outside of the divider is the grain-wheel 39. 'Io the spindle 40 ci' thegrainwheel is hinged a rack-segment, 41, pivoted to a stud, 42, and `having an arm, 43, forming la lever by which the main frame can be raised Secured in line with they 'I OO and lowered on the grain-wheel for regulating the height of cut. Strapped to the side of the divider is aspring-bolt, 44, engaging the racksegment. The bolt is retracted by a hinged arm, 45, connected to a swinging bar, 46, having a rod, 47, by which it is coupled to a short lever, 48, hinged to the arm ofthe racksegment. Theplatform-I'rame is braced transversel y by a bar, 49, extending from the curved portion 3 to the portion 16 beneath the frame.

50 is the standard of the binder, mounted on a sliding section, 51, of the bindingtable 52, to permit the adjustment of the binderfor short or long grain. The binder is adjusted by means of a rock-shaft, 53, having an arm, 54, connected to a link, 55, on the standard, and an arm, 56, connected by a rod, 57, with a lever, 58, hinged to a stud, 59, on the main frame, which also supports a rack-segment,60, engaged by a spring-latch, 61, for holding the lever to its adjusted position and the standard stationary. The standard is formed with the usual arm, 62, and head 63.

Journaled in the arm 62 is the needle-shaft 64, which operates the needle-bar 65 in the head 63.

66 is the packer-shaft, supported on the short standard 67 at the standard end of the binding-table, and journaled in a bracket, 68, secured to the head 63 at the rear end of the table.

69 is the inner ejector-shaft, journaled in the standard and in a bracket, 72, at the stubble side of the head.

71 is the outer ejector-shaft, journaled in the brackets and 72. Extending from the shaft 66 to the shaft 69, and mounted thereon beneath the arm 62 and also outside the head, are the cam-track arms 73, provided with cam-tracks 74, sprocket-wheels 75, endless chains 76, and forwarding-fingers 77. The cani-track arms outside the head haveaswinging track, 78, suspended from the cam-tracks by links 79, and from alifting-rod, 80, supported by a lever, 81, having slot 82 at its outer end receiving a pin, 83, on the head 63, and at its inner end provided with a wristpin, 84, working in a groove, 85, in acam, 86, secured to the needle-shaft and constructed in the back of the needle-driving crank. EX-

tending from the inner ejector-shaft to the` outer ejector-shaft are the cam-tracks 87, provided with sprocket-wheels 88, endless chain 89, and discharging-arms 90. Hinged to the inner ejectorshaft, between the cam-tracks 87 and the cam-track arms 73, are the retainingfingers 91, having pins 92, and supported by cams 93 on the outer ejector-shaft, having grooves 94, in which the pins engage. Parallel with the needle-shaft, and mounted in brackets 95,'secured to the standard and head, is anothershaft,96,havingacrank, 97, on which is suspended a link, 98, supporting a springbar, 99, hinged to the inner ejector-shaft by a coil, 100, at its middle portion, and extending downward to provide a compressor for the bundle formed thereunder.

In Figs. VIIb and VIIC I show a modification in the construction of the retaining-fingers and compressor, in which the retaining-fingers and compressor are combined.

99 represents compressor and retaining-iingers hinged by coils 100d to pin 92,working in the grooves 94 of cams 93, secured to the shaft 71. The pin 92a is supported in the ends of arms or bars 91, mounted upon the shaft 69. The inner ends, 100e, of the fingers 99" are se cured to a cylinder, 100", which is supported by a piston-rod, 98, hinged `to the crank 97 of the compressor-shaft 96. Within the cylinder, between its head 100c and the piston 100", I place a spring-coil, 100, for holding the fingers in normal position until operated. Supported in bearings 101 on the standard and head and extending over the arm 62 is a rockshaft, 102, having an arm, 103, alongside of the head, on which is supported atrp-arm or trigger, 104, by means of a rod, 105, the triparm or trigger being hinged to a stud, 106, onthe lower portion of the head. 107 are hangers on the sliding portion 51 ofthe table, in which is mounted the knotter-shaft 108, operating a knotting mechanism, 109. 110 is the needle-slot.

On the top of the standard are supports 111, having bearings for ashaft, 112, on which arms 113 are hinged. In the inner ends of said arms is journaled the reel-shaft 114, mounted on a suitable adjustable support. (Not shown.) A sleeve, 115, secured to the arms, is formed with a stud, 116, working in a slot, 117, in an arm, 118, on which it is guided.

119 and 120 are sprocket-wheelson the shaft 112 and reel-shaft 114, respectively, connected by an endless chain, 121. The reel-shaft has arms 122, to which are secured the bats 123 by knuckles 124 and straps 125 at their outer ends, and by hinges 126 at their inner ends. The cutter-bar 21 is operated by a pitman, 127, connected ith the wrist-pin 128 on a crank, 129, secured to a shaft, 130, journaled in the neck portion 31 of the frame.

131 is the inner roller of the endless apron 131", having a shaft, 132, extending across the main frame lengthwise of the table.

The various parts are operated by the following means: On the inner side of the driving-wheel vis an interior gear, 133, meshing with a gear-wheel, 134, on the shaft 35, having at its inner end a bevel gear-wheel, 135, meshing with another bevel gear-wheel, 136, on a shaft, 137, having a gear-Wheel, 138, meshing with a gear-wheel, 139, on the crankshaft 130, and provided with a sprocketwheel, 140, driving an endless chain, 141, passing over asprocket-wheel, 142, on ashaft, 143, under a pulley, 144, over a sprocket- Wheel, 145, on the packer shaft, under a sprocket-wheel, 146, on the apron-shaft, and over the sprocket-wheel 147,which is mounted on a shaft, 148, and back to the sprocketwheel 140.

At the inner end of the shaft 148 is secured v157, having pins 158 on the outside of the standard. l On the front end or outer end of the needleshaft and keyed thereto isa mutilated gearwheel 159, having a segment-gear, 160, cover-` ing a portion o'f its periphery, and provided on its inner side witha trip-hook or latch, 161, pivoted to its rim, pressed inward to engage a pin, 158, on the cross-bar by means of a spring, 162, bearing against its heel and held from engagement by means of an arm,- 163, on the trip-shaft, bearing on the projection 173 on the hook. 164 is a gear-wheel on the compressor-shaft, and 165 is a gear-wheel on the inner ejector-shaft engaged by the segment-gear of the mutilated gear-wheel 159. These gear-wheels 164 and 165 are provided with delay-shoes 166 and 167, respectively, bearing on the side of the toothless or plain portion of themutilated gear-wheel. Parallel with the vertical shaft 154 is another shaft,

Keyed to the compressor-shaft 96 is a bevel gear-wheel, 169, meshing with a bevel gearwheel, 170, on the upper end of the vertical shaft 168, having a bevel-pinion, 171, at its lower end meshing with a bevel-pinion, 172, on the knotter-shaft 108. The wheels and shafts move in the'directions indicated by the arrows.

The operation of the machine is as follows: rllhe grain being presented to the cutters by the adj nstable reel, the falling grain is received upon the main apron and fed to the packers or fmgers 77, which transfer it to a position under the trip or trigger 104, compressor 99, and retainers 91, against the twine between the gripper (not shown) and the needle, and in rear ol' discharging-fingers 90. As the grain accumulates under the trip or trigger, it gradually raises it until the arm 163 is disengaged from the projection 173 on the hook 161 of the mutilated gear-wheel, permitting the hook to drop in advance of a pin, 158, on the cross-bar 157 ofthe loose motive wheel 156. The pin, coming in contact with the hook, pulls on the l mutilated gear-wheel 159, causing it to turn,

together with the needle-shaft, simultaneously depressing the needle-bar to deliver the twine to the knotting mechanism and lifting the track 78 of the packers to stop the feeding of the latter. The gear 160 next revolves the wheel 164, which simultaneously operates the kn'otting mechanism and compressor, the latter tightening'or compactingthe bundle for permitting the knetter to take the twine (sufficient for knotting) from around the bundle,

the two ends of the loop being held by the gripper and needle until the knot is secured, and then the twine is severed. The continued rotation of the mutilated gear-wheel brings its f gear into mesh with the gear-wheel 165, which simultaneously causes the cam 93 to operate to lift the retaining-fingers 91 out of-the way Aof the bundle, and advances the dischargingfingers 90 to discharge the sheaf. vAfter the sheaf is discharged the various parts assume their normal positions Aby the time the wheel 159 reaches the position in which the arm 163 arrests its movement by falling in the path of the-.projection on the hook, the rotation of the gear-wheels 164 and 165 being arrested by the delay-shoes bearing on the plain portion of the rim of the mutilated gear-wheel.
